uglify-es-loader
Uglify loader for webpack(fork from uglify-loader, using terser@3)
To install

Use Case
Webpack has UglifyJSPlugin that uglifies the output after bundling. In the applications that depend on thirdparty libraries you may want to uglify with mangling only your application code but not the code that you don't control.
Example
Webpack 1
module: loaders: // I want to uglify with mangling only app files, not thirdparty libs test: /.*\/app\/.*\.js$/ exclude: /.spec.js/ // excluding .spec files loader: "uglify"
You can pass UglifyJS parameters via 'uglify-es-loader' property of webpack config.
module: loaders: // I want to uglify with mangling only app files, not thirdparty libs test: /.*\/app\/.*\.js$/ exclude: /.spec.js/ // excluding .spec files loader: "uglify" 'uglify-es-loader': mangle: false
Webpack 2
module: rules: // I want to uglify with mangling only app files, not thirdparty libs test: /.*\/app\/.*\.js$/ exclude: /.spec.js/ // excluding .spec files use: 'uglify-es-loader'
You can pass UglifyJS parameters via loader options.
module: rules: // I want to uglify with mangling only app files, not thirdparty libs test: /.*\/app\/.*\.js$/ exclude: /.spec.js/ // excluding .spec files use: loader: 'uglify-es-loader' options: mangle: false
